jVi allows vi/vim user to
be immediately comfortable in
the NetBeans editor, while having IDE editing features such as code
completion and hint/error markups and corrective actions. There are 200
normal mode
commands including vim's
visual block mode, tag stack and external process commands and filters
as with the "!" commands; see recent
changes.

For NON-vi/vim users who wish only to
use jVi's extensive
Rectangular Edit functions there is
javahelpset
on Block Mode
with examples and instructions on how to temporarily
enable jVi only
for Rectangular Edit functions.
